Triangle Angle Sums

This maths teaching pack for Key Stage Two gets the children to identify and calculate the size of some of the different types of angles that can be found in a range of triangular shapes including equilateral and isosceles triangles.

The class can model how to use number calculations to record the sets of angles in the vertices of a triangle to match the sum of one hundred and eighty degrees.

Download this teaching pack including classroom activities and an interactive presentation to identify and calculate the size of some of the different types of angles that can be found in a range of triangular shapes including equilateral and isosceles triangles

Activities in this teaching pack include a set of differentiated worksheets to record how to calculate the size of angles that comprise the vertices in different triangular shapes using addition and subtraction calculations that match the sums to one hundred and eighty degrees.

The interactive presentation gets the children to explore how to calculate the size of the different angles that can be found in a range of triangular shapes.

This lesson is part of a maths scheme of work to get the children to identify, record and classify some of the different types of angles that form the individual properties of a range of 2D shapes. There are teaching activities for shared learning, differentiated worksheets to support independent learning and interactive presentations to introduce concepts and key skills.
